The world was built on ideas and in the absence of innovation, mankind would have continued to live in stone age.

Of course, Rostow Ravanan, chief financial officer of Mindtree, would subscribe to the view that new ideas are absolutely necessary to promote business growth. Well, who wouldn’t? While talking to journalists at Reuters India Investment Summit, he vigorously defended his company’s foray into designing smart phones saying it is a new idea, which may as well pay off.

As the old adage goes, it is easy to build a new house as compared to remodeling an old one. If one would like to extend this adage to the new-age IT industry, then we could use what L. Ravichandran, president, IT Services of Tech Mahindra, told the Journalists at Reuters India Investment Summit in Bangalore: it is easy to negotiate new contracts with the clients rather than renegotiating old ones. He likened the new contracts to that of a honeymoon — both the customer and the service provider are happy. But, of course, he did not extend his metaphor to old contracts by likening it to a marriage gone vinegary.

Ravichandran also pondered over the fate of fixed lines telephones. According to him, the fixed line phone will not be done away with altogether. Instead, it will be increasingly used to deliver other digital services like broadband internet, IPTV etc. So in a perverse way, landlines may continue to be used, but not much to make phone calls though.

After completing the Mumbai leg, the 2010 India Investment Summit is set to arrive in the garden city of Bangalore on Wednesday. Long known as the pensioner’s paradise, Bangalore is fast morphing into a global, multicultural city. The city is also emerging as a favourite destination among young Indian professionals aspiring for a blue-chip career in the information technology business. But despite Bangalore’s success in the IT industry — the showpiece of a rising India — the city’s infrastructure has not been able to keep pace with its phenomenal growth over the last decade or so. Frequent power cuts, traffic-choked roads and lax urban planning often leave city dwellers and foreign investors in mute frustration. However, despite these issues, multinational companies have kept their faith in the city.

Executives of real estate, technology and pharmaceutical firms will be exclusively talking to Reuters journalists about their companies’ growth plans, challenges they face and business opportunities that are available within the wider context of India investment story.
